Let's compute the work $W=\displaystyle\int_C \mathbf F\cdot d\mathbf r$ with $$ \mathbf F=(x+2y)\mathbf i+(x-y)\mathbf j,\quad x(t)=2\cos t,\; y(t)=4\sin t,\; t\in[0,\pi/4]. $$ First find $\mathbf r'(t)$: $$ \mathbf r'(t)=\big(-2\sin t\big)\mathbf i+(4\cos t)\mathbf j. $$ ____ _______ _____ ________ __________ _______ ___ ________.
